Great for my dog
I had been using the 2500 for my 12yr old border collie to help with the arthritis is his back legs. We switched to the 6000, and was able to halve his dose with the same positive effect. Prior to starting him on green lipped mussel, he was limping daily and wouldn't run at all. Now he runs around with our young dog every day, and hasn't limped in over a year. He gets 2 capsules a day, they're easy to open and sprinkle over his food, and he seems to like the taste. I'd highly recommend these.
